FullEnrich, and why connect it to Claude
FullEnrich is a waterfall enrichment service: hand it a name and a company and it queries a chain of data providers in sequence until one returns a verified email or mobile number, then charges you only for the hit. It exists because no single vendor covers everyone, and stitching six of them together yourself is a job nobody wants.
Connecting Claude to it closes the gap between judgment and contact data. Claude is good at deciding who matters, which accounts fit the ICP, which titles own the problem, what the angle is. It is not a phone book. FullEnrich is the phone book. Together, the agent that just scored an account can also come back with the champion's verified email and a mobile, and the rep starts from a reachable person instead of a name.
Three ways to wire Claude to FullEnrich
Three ways to wire Claude to FullEnrich, from a hosted MCP server you authorize in the browser to a Clay column you already know how to use.
The hosted MCP server
FullEnrich runs an MCP server at mcp.fullenrich.com/mcp. Add it to the Claude apps or Claude Code, sign in with your FullEnrich account in the browser, and Claude can search contacts and companies, enrich one record or a batch, and export to CSV or JSON. Searches preview the first ten results and the total count for free; enrichment asks you to confirm before a credit is spent. Best for on-demand work from a chat.
The API, via Claude Code or the Agent SDK
For the scheduled version, call the FullEnrich API from the agent that runs your play: score the account list overnight, enrich only the contacts that clear the bar, write the verified emails onward to the CRM or the sequencer. You own the budget logic, which is exactly where you want it when credits are involved.
Inside Clay
If your lists live in Clay, FullEnrich is already a provider in the waterfall. Claude does the judgment in one column, FullEnrich fills the email and mobile in the next, and Clay's own review step gates the push to your CRM. Least plumbing if Clay is home.

Read first, write on purposeThe line to hold here is about money more than data. Let Claude search and preview freely, because previews are free, and keep the enrichment call, the thing that spends credits, behind an explicit yes until you trust the filter in front of it. An agent that enriches everything it finds is a very fast way to turn a monthly credit pack into a Tuesday.
What you can do once they're connected
Verified emails and mobiles for the exact contacts Claude has already scored as worth the conversation, no bulk enrichment of the whole list.
A pre-call brief that ends with a reachable person, not a name and a shrug.
Batch enrichment on a schedule: the overnight scorer hands its shortlist to FullEnrich and the sequencer wakes up to real addresses.
One conversation from search to export, with a confirmation step before any credit is charged.
What to build with FullEnrich and Claude
Each is a full playbook or skill you can ship, wired to FullEnrich.
Build an ICP list with Clay
Claude scores the rows, FullEnrich fills the verified email and mobile in the next column.
Personalize cold email with Clay
Personalization is worthless to a bounced address; verify before you write.
Account brief from a URL
End the brief with the champion's verified contact details instead of a LinkedIn link.
Inbound lead enrichment & routing
When the form gives you a personal email, find the work one before you route.
Gotchas worth knowing first
- Credits are per hit, so the filter in front of the enrichment call is where the money is saved. Score first, enrich the survivors, never the whole list.
- Searches preview the first ten results free; the export is what costs. Design agent prompts to look before they buy, and to ask you before the batch.
- A verified email is a point-in-time fact. People change jobs; re-verify before a big send instead of trusting last quarter's export.
- Mobile numbers carry consent and regional rules that email does not. Enrich phones only for the plays where a rep will actually call, and know your jurisdiction.
Claude + FullEnrich: common questions
Does Claude integrate with FullEnrich?
Yes. FullEnrich hosts an MCP server at mcp.fullenrich.com/mcp that you can add to the Claude apps or Claude Code and authorize with your FullEnrich login. From there Claude can search, enrich, and export. You can also call the API from an agent, or use FullEnrich as a provider inside Clay.
Will Claude spend my credits without asking?
Through the MCP server, no. Searches preview ten results and a total count for free, and the enrichment step asks for your confirmation before anything is charged. If you build on the API, that confirmation is yours to add, so add it.
What does a FullEnrich export cost?
FullEnrich lists 0.25 credits per contact or company exported through the MCP server, the same rate as the API. Only verified hits are charged in the waterfall, which is the point of a waterfall.
Should I use FullEnrich through Clay or directly?
If your lists already live in Clay, keep it there: FullEnrich is a provider in the waterfall and Claude is the reasoning column beside it. Go direct, through MCP or the API, when Claude is running the play and enrichment is one step inside it.
What is the first play to run?
Take the ICP list Claude already scored, enrich only the top tier, and hand the verified emails to your sequencer. It proves the pattern, score then enrich, and it shows the credit savings on day one.
